TADDM OMP Change Event Module on TADDM 7.1.2

The TADDM OMP Change Event Module (http://www-01.ibm.com/software/brandcatalog/portal/opal/details?catalog.label=1TW10CC1Q) is a module you install on TADDM servers so that you will get alerts on various monitoring systems when a change (any change or specific changes) are detected.

This module works very well on TADDM 7.1, but it fails on TADDM 7.1.2.

The error message is:
com.collation.proxy.api.client.ApiException: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: invalid method hash
at com.collation.proxy.api.client.DataApiImpl.findModel(DataApiImpl.java:954)

Apparently there were changes in the Java files between 7. 1 and 7.1.2.

The solution is to change following line in /bin/changeevents.sh:

omp_classpath=.:"$TADDM_PATH"/lib/platform-model.jar:"$TADDM_PATH"/lib/api-client.jar:"$TADDM_PATH"/lib/api-dep.jar:"$TADDM_PATH"/lib/edm-server.jar:"$TADDM_PATH"/lib/oal-api.jar:"$TADDM_PATH"/lib/oal-common.jar:"$TADDM_PATH"/lib/oal-topomgr.jar:"$JAR_DIR"/evd.jar:"$JAR_DIR"/log.jar:"$JAR_DIR"/taddmomp.jar

to

omp_classpath=.:$TADDM_PATH/sdk/clientlib/taddm-api-client.jar:"$JAR_DIR"/evd.jar:"$JAR_DIR"/log.jar:"$JAR_DIR"/taddmomp.jar

Hope this helps whoever encounters this problem.

PDFs

I read a lot of things which are written in Portable Document Format, some relevant to my work and some to my studies.

In any case, I often find myself wanting to "do something" with the PDFs - copy specific pages, modify or add something.

The proper way of doing this used to be using Adobe's programs - but these are expensive.

Here's a link to a list of tips relevant to PDF manipulation.

I've never really wondered how the did multiplication...

http://scienceblogs.com/goodmath/2008/12/roman_numerals_and_arithmetic_1.php

But now that I've read about it - it's fascinating...

It's amazing how some things that seem so obvious and second nature are actually really very dependent on the time and culture one comes from.

No wonder it's difficult for different ethnic groups to get along :(

How writers, artists, and other interesting people organize their days.

This is one of the best sites I've found in quite some time.

I'd like to be a in the Scientists & Mathematicians in that list, but for now I'll have to make do with being a procrastinator...

Ancient Rome on your Modern Computer

Google has added a new twist to its popular 3D map tool, Google Earth, offering millions of users the chance to visit a virtual ancient Rome.

 

Google has reconstructed the sprawling city - inhabited by more than one million people as long ago as 320 A.D..

Users can zoom around the map to visit the Forum of Julius Caesar, stand in the center of the Colosseum or swoop over the Basilica.

A planetary snapshot

Since Copernicus showed that the Earth orbits the Sun, we've known that we're not the only planet in the universe. 20 years ago was the first discovery of an exo-planet - a planet which orbits a different star. Over 350 of them have been discovered over the years. BUT... until this week, all these discoveries were made with various techniques which detected the planet, but did not show it. This is similar to knowing that an airplane is flying near you because you can see it on radar or see it's contrail, but not ever seeing one.

Last week the Hubble Space Telescope took a picture of Fomalhaut and saw .. really saw a planet.
